I AUTOMOBILE CHASSIS.

Application filed March 15, 1922. Serial No. 543,893.

T 0 all whom it may concern:

Be it lmown that we, Hnivnn; N. GARsoN, a. subjectv of the King of Norway, and THORVALD N. GARsoN, a citizen of the United States, and residents respectively of New York city, State of New York, and St: George, borough of Richmond, city and State of New York, have invented certain. new and useful Improvements in Automobile Chassis, of which the following is a specification. Y a

The purpose of the invention is to provide a truck or pleasure car chassis capable of carrying heavy. loads, and of such designthat driving shocks transmitted by the passage of the wheels over irregularities in the road surface will be largely absorbed. Further objects of the invenion will hereinafter appear. I

The invention will be understood .by ref-- erence to the accompanying drawings in which I b Fig. 1 is a diagrammatic plan View of a chassis embodying the improvements, and

Fig. 2 is a side elevation of the same.

3 is a fragmentary longitudinalsectional view of one of the tubular frame members enclosing the load-carrying and bumper springs. I

Fig. 4: illustrates the rear transverse frame member,.in side and front elevation.

Fig. 5 is a side elevation, partly in section of a rear rockerarm.

Fig. 6 is a sectional plan view of one of the spring actuating rods, illustrating diagrammaticallyits connections with a rocker arm.

Fig.7 illustrates in elevation and in sectional plan one of the slide-bushings dis-- posed in practice intermediate aspring actuating rod and its appropriate rockermrm.

In the present construction, a set of two load carrying .springsand a set of two bumper springs are providedfor'each wheel. These springs are disposed within two parallel vertically spaced tubes at each side of the chassis and in themselves constituting the side chassis frame members The stresses are distributed over the said slde frame niembersinasmuch as the load carrying springs in the lower tube are arranged at the opposite ends thereof, the bumper springs being intermediate, whereas in the upper tube the load carrying springs are intermediate and the bumper springs are at thev opposite ends of the tube.

Referring to Figs. 1 to 3 of the drawings, it will be seen that the chassis comprises side framemembers consisting ofa lower tube 1 and an uppertubeli The side frame members are rigidly connected by'means of front and rear cross. frame members. The front cross frame member 3 is U-shaped, a depending extension being provided at each side, said extension being providedwith a sleeve 2 for reception of the A stud 11 is loosely fitted within a suitable bearing aperture formed in the trunnion and is threaded within the cup-like end 6 of the rockers. By this means the front axle is so mounted as to be capable of oscillation alternately upon each stud 11. Thus when one of the wheels passes over an obstruction, the axle and the rocker arm nearest the wheel. will be movedupwardly therewith; the opposite end of the axle, however, will merely oscillate upon the stud 11 at that end, as an axis. The rear axle is similarly mounted, as will hereinafter appear, and in this manner the transmission of torsional stresses and shock to the frame is largely reduced.

.Each front rocker is formed with an upwardly projecting lug disposed beneath a cushion 12 secured to frame 3 and thus providing a limit-stop for the rocker.

It will be seen that each spring actuating IOd 14 is formed intermediate its length with a head 1;) and that the head is adapted to engage two springs, a load carrying spring- (r and a bumper spring Z) these springs being disposed within the appropriate side frame tube. The outer end of each spring-actuating rod is forked 6) to embrace the ap )ropriate leg 16 of its rocker. The said leg also is formed with a forked end, the opposed walls 17 of which are channeled at i?" to receive the ribs 18 of a slide-bushing- 19. The forks of the spring actuating; rod are apertured to receive a stud 2:2 which passes through the slide bushing and thus forms the primary connectingunit. The extent of movement of bushing 19 is limited by a cap 20 secured to the rocker by screws 21. By this construction compensation is provided for the slight variations in distance between the axis of the rocker and the endof the rod due to the arorfite movements of the rocker, thus avoidingthe necessity of a link intermediate the rocker and the rod permitting lateral movement of the rod.

The inner end of each m ning-actuating rod is guided within an axial aperture 22 formed in an appropriate internal reinforcinfg" block 23, the said blocks being; disposed within the tubular frame members substantially cent-rally thereof as shown in l 1 and 2. p

The tubular frame members at their rear ends are rigidly connected by means of the cross frame member B illustrated in Fig. ibeing received within the sleeves The connections between the rear spring actuatmg rods and the rear rockers 25 are the same as those in the front of the chassis and as illustrated in Figs o and 6. Each rear rocker is fulcrumed at 26 between lugs 27 projecting from the cross frame member B, and is formed with a cupped end to receive the annular end of a trunnion 28 secured to the rear axle housing 29, in underslu'ng position, by means of the straps 30. A studsorew 31 passes through the bearing aperture of the trunnion, in each case, and is threaded within the cupped end of the rocker. Thus the rear axle may oscillate upon the studs as hereinbefore described with respect to the front axle and its con nections.

What we claim is:

1. in an automobile chassis, a frame including two horizontally arranged and vertically spaced tubular side frame members, supporting wheels, a spiral load carrying spring horirontall supported by each side frame member, a. rocker mounted on the fre we and connected to a wheel, and an operative connection between said rocker and each of said springs.

, In an automobile chassisga frame comtWo horizontally arranged and vertically spaced side members, a load carrying springhorizontally supported by each side frame member, supporting wheels, and connectin means intermediate 11 wheel and each of said springs, including a rocker mounted on the frame.

3. In an automobile chassis, a frame, two tulmlar horizontally arranged and verti- I spaced members at each side of the frame, coiled load carryingspring within each tubular member, supporting wheels, and connect no means intermediate a wheel and each of said springs, including a rocker mounted on the frame.

4, In automobile chassis, frame corriprisino.- side members, each side member consistino; of an upper and a lower tube, a wheel, rocker carried by the frame, a spiral load carrying spring within each tube, rods within the coils of the load car ryinp; springs and each having a head at gaging its appropriate spring, and a rocker mounted on the frame and having connections with the rods and with the wheel. I

5. in an automobile chassis, supporting wheels, a frame comprising side inembers each consisting of an upper and a lower tube, a spiral load oarr ing spring within each tube, front and rear cross frame members, a plurality of rods each within the coils of a load carrying spring and having a head said spring, and jliirality of rockers, each. rocker being pivoted to the frame and being connected to two of said rods and to a wheel.

6, In an automobile chassis, supporting wheels, a frame comprising side members each consisting of an upper and a lower tube, a spiral load CFLII'YlDQ, spring within eachtube, a front and rear cross frame'meinbers each formed with four spaced sleeves to receive the tubes, a plurality of rods each within the coils of a load carrying spring and havinpa head engaging said spring, and plurality of rockers, each rocker being pivoted to the frame and beingconnected to two of said rods and to a wheel.
